Joshua and Brandon buying a pizza for their math class. They will spend $77. Joshua will pay six times more then Brandon. How much will Joshua pay?

$66

Step-by-step explanation:

For this problem, we will simply write two equations to solve how much each person will pay.

Let x represent the amount of dollars joshua pays and y represent the amount of dollars brandon pays.  Then we can say the following:

x + y = 77

x = 6y

Using these two equations, we can solve for how much Joshua will pay.

x + y = 77

6y + y = 77

7y = 77

y = 11

x + y = 77

x + 11 = 77

x = 77 - 11

x = 66

Hence, Joshua pays $66 and Brandon pays $11.

Cheers.
